I found the following script which builds a universal version of libjpeg.
It does this by building a PPC and a i386 version and lipo'ing them
together.  This came from http://www.omnigroup.com/mailman/archive
/macosx-dev/2007-May.txt

#
#       jpeg-build-univ
#
#       Script to crteate universal binary version of libjpeg.
#
#   ? 2006 Alan Staniforth
#
#       Version 2.0
#
#       Invoke thus:
#
#       jpeg-build-univ [-h] | [-v] | [-i] [-p prefix] [-s sdk] [-n] [-k]
#
#       where   prefix is the install root for the libraries.
#
#       Version 2.0:
#               Source download incorporated.
#               Reverted to using MacOSX10.3.9.sdk as the default SDK for
PPC
#               Targets 10.2 for ppc, 10.4 for i386.
